Deleting Jenkins jobs through GUI does not delete their workspaces in slaves

Question

I recently deleted 2 job from Jenkins (via GUI). When I log into slaves afterwards I still see workspace of those 2 jobs lying around. Is this behavior normal?

Notes:

Answer 1

I came across an effective script that does a good job of only cleaning when disk space gets low and brings the slave offline: https://gist.github.com/rb2k/8372402
